The herb comes from the inner bark of a tropical tree native to West Africa. It has been used for many centuries for various medicinal purposes.
Today yohimbe cream and tablets are used as sexual enhancement products. Specifically they are used to treat erectile dysfunction and stimulate the desire for sex.
The active ingredient of yohimbe is an alkaloid called yohimbine. Although this compound only makes up less than 10% of the herb, it is the only component that appears to have any therapeutic benefits. Yohimbe and yohimbine are used interchangeably to describe these products.
